I know this isn't going to be a popular thread fro me but here goes. Better get use to it because Tetra-ethyl lead isn't a great substance to leave behind us when we are gone and gentlemen it's imprint is there for a long time, it's being ingested by millions of people every day, it's one of the nastiest product ever introduced in our environment. I for one being a responsible racer doesn't want anyone to shove it down our throat anymore than anyone else but it's a fact that we can live without it. General Motors has spent millions of dollars(before they become Government Motors) in studies confirming that no evidence of valve seat recession cause by removing of tetra-ethyl in racing or conventional usage gasoline. Most engines that had factory-installed hardened valve seats,and many flame hardened cast iron seats survived the elimination of lead, although when the flame hardened seats were resurfaced they were more inclined to recession problems mostly caused by an overaggressive mechanic or engine builder with a new valve seat tool.Run lead free Avgas for a fifth of vp racing fuels. It's my opinion and I know what is said about opinions. Claude Ruel
